摘要

After hot rolling, stainless steel coils are covered by oxide which needs to be removed to ensure the quality of the subsequent steps of the manufacturing process. Mechanical pickling (or descaling) of the coils is thus performed on the first annealing and pickling line,. The oxide layer is generally removed by shot blasting and chemical pickling. For the shot blasting step, the shot is blasted on the steel by several turbines positioned on the line. This ensures the quality of subsequent cold rolling, improves surface quality, prevents corrosion and improves visual aspects.
